Drawing View- 1
In this view, I have applied the target datum (A1, A2, A3) of Ø60mm.
I have applied the datum of A, B, C, D.
GD&T features used in this drawing view

• Perpendicularity
• Flatness
• Position

Drawing View- 2
In this view I have applied datum A, and applied the profile of the surface opposite to the datum A.
For Basic DIMN 225, we need to take the tolerance half of the profile of surface tolerance.

In this view I have applied the position tolerance along the datum axis of B, C & D.
Basically constraining the hole axis of the opposite surface of datum A.
